FTP Access - How do I get it from outside the network?

I have just set up the FTP service on my 10.5 Server. I can connect to it from inside the network by using the fully qualified domain name, but I don't know how to get to it from outside the network. How do I know what IP I would use? We have static IP at the location?

depending on whether you are using active or passive ftp you might need to open up more ports as well. Look at webdav as an alternative. I moved to this after having trouble getting ftp to work reliably without opening up lots of ports.
